A centrifugal field-flow fractionation device includes: a rotor having a rotation axis, the rotor being provided to be rotatable about the rotation axis; a cover covering the rotor; a protective member arranged inside the cover to over the rotor about the rotation axis; a shock-absorbing member arranged between the protective member and the cover; and a fixing part provided in a breakable manner to fix the protective member to the cover. The rotor is arranged such that the rotation axis orients in a horizontal direction. In a case where a part of the rotor disintegrates and is brought into contact with the protective member during the rotation of the rotor, the fixing part breaks to cause the protective member and the shock-absorbing member to move with the rotor while receiving the impact of the rotor to buffer the kinetic energy of the rotor.
